Dark Matter should be returned to gathering points.

I agree.

Dark Matter should still come from Gathering points.

Repairing a set of gear costing 4200gil is also a big issue. That would have been 42,000 gil in 1.0 money - a ridiculous sum.

It was 5000 gil per piece of level 50 gear in 1.0, so it's really not much different doing a repair all. Even now at least it scales based on the percentage of durability.

As far as DM goes, I don't care one way or the other. Right now crafters have the option of buying the DM to repair their own gear or using a repair vendor. I don't know if it needs to be more involved than that. There was obviously a reason why SE removed DM from gathering points.
